A rock turns to a sedimentary rock through the rock cycle when erosion occurs. Erosion is when a rock get destroy by water the rock turns to be like sand
Sedimentary rock is basically rock formed from cemented particles of weathered and eroded rocks of all three rock types. There are exceptions, however.
By exposure to heat and/or pressure through depth of burial, directed pressure, or proximity to a magma source. Existing minerals can recrystallize, non-hydrous minerals can replace hydrous minerals,...
Igneous rock, when exposed, will weather into smaller particles by mechanical and chemical means. Eventually the particles will be eroded and be transported by wind, water, ice, and gravity and...
